While the upper section provide access to each main filter's direct output, the lower section has 4 voltage controllable parameters to manage two independent functions for further spectral editing: tilt and parametric scan.
The tilt, as the name suggest, tilts the spectrum, adding and subtracting amplitude to the 16 bands, emphasizing lower or high bands, and attenuating high or lower bands: this is managed only with the green potentiometer.
The parametric scan, instead, works with three parameters: peak/notch, band selector and width. Like in a parametric equalizer, where is possible to set peak/notch gain, frequency and slope, the FUMANA uses three parameters to set which is the centre band to perform this manipulation, then if that band should be emphasized or attenuated, and how this action is extended to nearby bands.
In addition to the 16 bandpass outputs, there are other 4 outputs provided: the all bands output, the all envelope followers output, the odd bands and the even bands output. These two have the options to be inverted in phase with two switches, in order to obtain even more combination when summed together, maybe/also with the "all bands output", using, for example the 333 module.
Since a spectral transfer tool may be used as a "vocoder-like-effect", the FUMANA provides an input for an external noise which may be used for unvoiced (fricative/sibilants) sounds as words containing or starting with s, f, z, ch and other fricative sounds.
It is composed of three identical sections, the red, yellow and green, each of those featuring three inputs summing amplifier with three independently buffered outputs.
Derived directly from the CGM creative mixer series, the sum section is DC coupled, allowing the sum of control voltages as well as audio signals.
With an extremely low tolerance in both sum and output sections, it is suitable also for summing quantized voltages like the ones coming out from the quantized outputs of the SAPEL.
In case CVs or audio signals are particularly hot, the 6dB attenuator might be helpful to reduce exactly by 50% the incoming signals.
Red and yellow output are also normalled to the 1st jack socket of the yellow and green input: in this way this module can also work as a 1 to 9 buffered multiple.
The Channel manages mono signals via the 3.5 mm input mono jack. It has a main stereo VCA with CV in and attenuator (RED), a direct output post main VCA (pre or post fader), two parallel sends with mono VCA with CV in and attenuator for each send and pre/post fader switch (YELLOW and GREEN), and a PAN control with offset CV and offset pot. This, together with the latching buttons for mute, solo in place, and PFL, manages the incoming signal and distributes it to the Group module.
Noise outputs are colour coded, based on the noise colours, and include:
- Blue (+3dB/oct spectrum)
- White noise (0dB/oct spectrum)
- Pink noise (-3dB/oct spectrum)
- Red noise, a.k.a. Brown or Brownian (-6dB/oct spectrum).
The random voltage and clock section features four uncorrelated random CV generation paths, divided in;
- Fluctuating random voltage;
- Quantized random voltage with 2n stages tuned in semitones referred to 1V/oct scale;
- Quantized random voltage with n+1 stages tuned in octaves referred to 1V/oct scale;
- Non quantized sample & hold.
It is also possible to set a probability distribution with a potentiometer, and apply (or do not apply) the chosen distribution setting to each of the four paths independently.
Furthermore, each of the two random sources section features an independent built-in clock generator, with clock output and random clock output, which can be used in "more than" or "less than" mode. It is possible to use an external clock signal as a clock source, bypassing the built-in one. In addition to that, it is also possible to hand trigger the clock via a manual sample & hold button, which can be also modulated by gate signals.
The Group gets and sums the L/R post fader signals (WHITE) of all the linked Channels, sums all the signals from the YELLOW and GREEN sends, and manages the sends (mono) and returns (DUAL MONO or STEREO), summing it to the signals from the CHANNELS. It also manages the solo in place activation on all the linked Channels, and provides a L/R output for the outgoing signal, or (via a jumper on the back of the module) a L/R output of the sum of the returns signals.
The Master sums the incoming signals from the Groups, and manages the PFL (stereo) of both Channels and Groups. It also features a stereo in via a 3.5 mm stereo jack with PFL latching button and a stereo out via 3.5 mm stereo jack for headphones, whose signal can be blended between PFL (BLUE) and main out (WHITE).
Three boards are included in each UNO case, with 3 flat cables (9 connectors each for the 84HP, 12 each for the 126HP). The boards are mounted inside each metal row without front panel in order to do not waste any precious HP.
